Abstract
One embodiment provides a method, including: obtaining EEG data from one or more single channel EEG sensor worn by a user; classifying, using a processor, the EEG data as one of nominal and abnormal; and providing an indication associated with a classification of the EEG data. Other embodiments are described and claimed.
Core Innovation
The disclosed invention coordinates electroencephalogram (EEG) signal collection using only four unitary wireless EEG sensors. The method receives a patient identifier and sensor identifiers, activates and pairs the four sensors to an interactive device, and provides instructions for positioning the sensors on a scalp at a left forehead, a right forehead, behind a left ear, and behind a right ear.
The interactive device controls the workflow, including quality assessment of signals recorded and relayed from each sensor, followed by recording EEG data and identifying seizure events from the collected data. The invention emphasizes per-sensor signal quality assessment and interactive guidance, and dependent refinements specify that sensors may be repositioned based on the assessed quality, with alerts and resolution instructions related to the quality of signals.
For downstream signal representation and processing, the invention supports automatically combining EEG signals from the four wireless EEG sensors to generate differential traces of interest. Each unitary wireless EEG sensor comprises two electrodes forming a single bipolar channel, and seizure analysis can be supported by generating and presenting individual and differential traces, with seizure events identified from the recorded data.
Claims Coverage
The provided excerpt contains two independent claims, a method claim and a non-transitory computer-readable medium claim. Across these independent claims, the core inventive coverage includes coordinated activation and pairing, interactive and quality-controlled positioning of exactly four unitary wireless EEG sensors, followed by signal quality assessment, recording, and identification of seizure events from the resulting EEG data.
Coordinated seizure detection with four unitary wireless EEG sensors under interactive-device control
receiving a patient identifier; receiving a sensor identifier for each unitary wireless EEG sensor of only four unitary wireless EEG sensors; activating and pairing the four unitary wireless EEG sensors to an interactive device; providing, via the interactive device, instructions for positioning the four unitary wireless EEG sensors on a scalp at a left forehead, at a right forehead, behind a left ear, and behind a right ear; assessing a quality of signals recorded and relayed from each unitary wireless EEG sensor; recording EEG data collected by the four unitary wireless EEG sensors; and identifying seizure events from the EEG data collected from the four unitary wireless EEG sensors, wherein the method is performed under control of the interactive device.
Non-transitory medium for interactive four-sensor seizure detection workflow
receiving a patient identifier; receiving a sensor identifier for each sensor of only four unitary wireless electroencephalogram (EEG) sensors that are in communication with the processor; activating and pairing the four unitary wireless EEG sensors to an interactive device; providing instructions, via the interactive device, for positioning the four unitary wireless EEG sensors on a scalp at a left forehead, at a right forehead, behind a left ear, and behind a right ear; assessing a quality of signals recorded and relayed from each unitary wireless EEG sensor; recording EEG data relayed from the four unitary wireless EEG sensors; and identifying seizure events from the EEG data relayed from the four unitary wireless EEG sensors.
In combination, the independent claims cover a coordinated four-sensor, unitary wireless EEG workflow with interactive-device controlled positioning, per-sensor signal quality assessment, EEG data recording, and seizure event identification, implemented either as a method or via instructions on a non-transitory computer-readable medium.
